After the update, i saw a warning from wpforo about db issues. After going to troubleshooter, i see none (fixed maybe).
In the log i see:
[11-Dec-2020 10:34:01 UTC] WordPress database error Table 'zzz.wp_wpforo_logs' doesn't exist for query SELECT DISTINCT `key`, `value` FROM `wp_wpforo_logs` WHERE `sessionid` = 'dsUmRXrXQP7Qq3SQVnVqA0vuHhn0fsFfgA0HRDPcDYq' AND `key` IN('neutral','error','success') made by do_action('admin_init'), WP_Hook->do_action, WP_Hook->apply_filters, wpForo->init, do_action('wpforo_before_init'), WP_Hook->do_action, WP_Hook->apply_filters, wpForoNotices->init
Is that a new table or something new? Since my DB was 100% allright.
Yes, this is a new table and I have no idea why it's not created on the plugin update process. It seems your MySQL server version is old. I recommend deactivate (do not use the Uninstall button), delete the current version, then search and install the 1.9.0 version again. It'll create the table on installation.
My server definitely is not old (Server version: 10.3.25-MariaDB-log-cll-lve - MariaDB Server, protocol version 10) but in any case it seems solved.
